WATER-GLASS GUARD.

Specification of Letters Patent.

Patented Dec. 4, 1906.

Application filed September 13, 1906. Serial No.334.4=50.

To all whom it may concern:

Be it known that I, WILLIAM G. I-IALLIDAY, a citizen of the UnitedStates, residing at Fort Madison, in the county of Lee and State ofIowa, have invented a new and useful Water-Glass Guard, of which thefollowing is a specification. 4

This invention relates to guards for watergages, and. its object is toprovide a simple and inexpensive device of this character which can bereadily fastened around a watergage and which when so placed will remainsecurely in position.

A still further object is to provide novel means for fastening the guardaround the gage, said means constituting a reflector whereby the heightof the water within the gage may be easily determined.

With the above and other objects in view the invention consists ofcertain novel features of construction and combinations of parts, whichwill be hereinafter more fully described, and pointed out in the claims.

In the accompanying drawings is shown the preferred form of theinvention.

In said drawings, Figure 1 is a front elevation showing the guard inposition upon a water-gage. Fig. 2 is a rear elevation of the guarddetached, and Fig. 3 is a section on line 3 3, Fig. 2.

Referring to the figures by characters of reference, 1 is the glass tubeof the gage, the same being mounted at its ends in joints 2 of the usualform and which communicate through pipes 3 with a boiler. (Not shown.)These parts are all of the usual or any pre ferred construction andconstitute no part of the present invention, which relates solely to aguard for surrounding the glass.

The guard consists of a strip of heavy metal fabric 4, the ends of whichare reinforced by metal rings 5, embracing the under edges of the strip.Reinforcing-strips 6 are also folded over and secured to thelongitudinal edges of the fabric 4 and have extending outward from themheaded lugs 7. An elongated back plate 8 is arranged to extend over thelongitudinal edges of the guard, and this strip has its inner facepolished, so as to constitute a reflector, while it is reinforcedtransversely and longitudinally by folding the edges thereof, as shownat 9. L-shaped slots 10 are out into opposite edges of the strip 8 andare adapted to receive the lugs 7. A semicylindrical plate 11 extendsdownward from and is rigidly secured to one of the rings 5 and has arecess 12 cut thereinto to form projections 13, adapted to straddle thelower joint 2 of the gage.

In using this device the strip 8 is first removed by pushing it upwardso as to enable the lug 7 to be withdrawn from the slots 10. After thestrip 8 has been removed the guard is grasped in the left hand with theslotted or open portion toward the operator, and the lower portion ofthe slot is then slipped over the water-glass just above the lower joint2. The guard is then slipped over the lower joint 2, and at the sametime the top portion of the guard is swung forward toward the operatorand will therefore inclose the full length of the glass. The guard isthen raised as high as possible and turned so that the slotted por- 7tion will be in position back of the glass and is then lowered to causethe projections 3 to straddle the joint 2. position upon the guardeither before or after the guard has been arranged with the open portionthereof back of the lass.

In removing the guard the strip 8 is first slipped out of engagementwith the lugs 7, after which the guard is raised and turned until theopen portion thereof is in front of the glass. The guard is then loweredas far as it will go, and the top portion thereof is pushed backward offof the glass 1, after which the entire guard may be lifted off of theglass. The parts when assembled are held securely in place, the ends ofthe strip 4 surrounding the alining portions of the joints 2, and ittherefore becomes impossible to detach the guard, even though the glassbe broken, without first raising it. It is therefore apparent that theguard constitutes an efficient protection against injury by brokenglass, &c., in the event of the breaking of the gage-glass. Moreover, byproviding the particular means for fastening the guard in place there isno necessity of utilizing screws or other fastening means. Anotheradvantage is the provision of the polished face upon the strip 8, sothat the same will act as a reflector to accurately indicate the heightof the water within the glass.

The preferred form of the invention has been set forth in the foregoingdescription; but I do not limit myself thereto, as I am aware thatmodifications may be made there- The strip 8 is placed in in Withoutdeparting from the spirit or sacrificing the advantages thereof, and Itherefore reserve the right to make such changes as fairly fall Withinthe scope of the claims.

What is claimed is 1. A guard for Water-gages comprising a metal-fabricstrip adapted to embrace a gage, i

extensions pro ecting from the adjoining edge portions of said strip,and a combined reflector and connecting-strip arranged'longitudinallyupon the fabric strip and having angular slots adapted to detachablyreceive the extensions.

2. A guard for Water-gages comprising a metal-fabric strip adapted toembrace a gage, extensions projecting from the adjoining edge portionsof said strip, a combined reflector and connecting-strip arrangedlongitudinally upon the fabric strip and having slots adapted to receivethe extensions, and means extending from one end of the guard forengaging a joint of the gage.

3. A guard for Water-gages comprising a metal-fabric strip adapted toembrace a gage, extensions projecting from the adjoining edge portionsof said strip, a combined reflector and connecting-strip arrangedlongitudinally upon the fabric strip and having slots adapted to receivethe extensions, and

an extension projecting from one end of the guard and adapted to bearupon a joint of the gage, said extension having projections adapted tostraddle said joint.

4. A guard for Water-gages comprising a strip of metal fabric adapted toembrace a gage, the edges of said fabric being reinforced, headed lugsextending from the adjoining edges of the fabric, a combined refiectorand connecting-strip disposed longitudinally upon said fabric andoverlapping the edges thereof, said strip having angular slots adaptedto receive the lugs, and a semicylindrical extension rigidly connectedto one end of the guard and recessed to receive a joint of the gage.

In testimony that I claim the foregoing as my own I have hereto aflixedmy signature in the presence of tWo Witnesses.
